Fuel additive Recommend?

I started a thread, a little while back, asking for advice regarding buying another car....
http://community.plus.net/forum/index.php/topic,94474.0.html
Well, the general consensus was to "hang on to the one I have got".... " better the devil you know"....
Yesterday, we returned from weekend away to North Wales, staying first at a place called Llangynog, about 12 miles east of Lake Bala,.... the journey there involved motorway driving at 70mph, dual carriageway driving 60mph and town driving at Huh mph...Variable stop start.
I topped up the tank before leaving, (brim full)  and reset the trip counter. After driving 283.3 miles, I again topped up the tank, with 20.0 ltrs (brim full) and also added my favourite Diesel additive.    the maths on that journey gave me a return of 63.80 MPG.....  Smiley
The following two days, we did some "touring" around the area, which included mountain roads, and "normal" A roads, (in Wales, these are very twisty and bendy - so variable speeds) .... No special or different driving techniques were used,.... just my "normal" way of driving.... when I had done 247 miles, I again topped up (brim full)  (including my Diesel Additive) with 17.56 ltrs.... giving me a return of 63.3 MPG...  Smiley
And eventually we came home via the A roads of Wales, down through Rhayader, Abergavenny, M4 to Bath, and then via Trowbridge,(stop start ) Salisbury ( stop start) , Southampton, and eventually the M27 for the final 25 miles to home,.... giving a final mileage of 263 miles and a final top up (including my diesel additive) 18.17 ltrs and a final return of 65.09 MPG.....  Cheesy
The Diesel Additive I use is called "Millers Diesel Power ECO MAX" .... it is a 500 ml container, and recommends 50ml per tank full.... costs about £10 but does 10 tank fills so only a £1 per tank fill....
Considering that before I used this additive, local driving around home gives me a return of about 57/58 mpg, and also considering the engine has done over 155,000 miles I think it is well worth the £10 to get figures as above...
There are a couple of other bonusses you get too.... the engine seems to be much more "responsive"... ( I do do a bit of "boy racer" stuff, just for the fun of it! ! )... and it cleans the Diesel Injectors, meaning that there is less pollution/smoke (my car does not smoke when booted.... unlike some more recent registered diesels I have followed !)...
So I can recommend it to any of you who want to improve your diesel car performance..... and of course your MPG.
(Oh and to be sure..... I`m not selling, or considering changing my car now ! ! !)  Cheesy

Re: Fuel additive Recommend?

Glad to see you've settled for keeping old faithful now! Diesel though?.. eww.. rattly engine sounds do nothing for me!
I'm a petrol man personally.. i like a nice smooth quiet engine. Yes it does cost a lot more MPG wise (and price and the pump wise Sad ) but its a lot nicer sound wise. 155k is nothing for a derv really these days. I see most dervs as being like volvo engines - good for 300k at least.
Back to the topic of additives, i'm thinking about going the LPG way if i can find a cheap way of getting it done as petrol is ludicrous these days. It would be nice to enjoy <£1 prices again.
I need a new signature... i'm bored of the old one!

@ shutter - when I ran diesels I regularly added injector cleaner to maintain good performance and still use it prior to MOT on current petrol car.

I've a petrol pump icon on my car's dash that notifies me whenever my credit card is approaching its limit. Roll eyes

Nice one !... What I need to do now is to "refine" my driving methods to get another 10% increase in MPG.... and then it will be well into 70 mpg...
Not sure about what diesels you have been "listening" to.... but mine is only slightly noisy when it is cold/cool/lukewarm..... after 30 mins it is lovely and quiet, and you would be hard pushed to complain about it when on the motorway/dual carriageway....
just done a google for LPG conversion... got this as first page...

If you are interested in an LPG conversion you must be willing to make a significant outlay – most LPG conversions cost between £1,500 and £2,000. However, many LPG enthusiasts claim this money can be recouped in one-two years with the money you save at the pump.

Re: Fuel additive Recommend?

I looked into the LPG conversion thing a while back. It's a myth that you have to have a certified installer do the job - i checked with the LPG association themselves.
What you must do however is notify the insurers and if requested the vehicle must be certified - IE inspected and a certificate produced by a qualified LPG installer. You CAN do a DIY installation and get it checked over just like installing your own petrol or diesel fuel system in a kit build car.

Re: Fuel additive Recommend?

Its also a myth that going Lpg will save you from any congestion charges/road tax relief. It will, but only if the car was factory fitted with Lpg from new. Currently the company doing that in the UK is/was Vauxhall (not sure if they still are or, if someone else is doing it now)
Other wise your car retro-fitted will attract congestion charges and road tax as it was when first registered. And don't forget to tell your insurance company, they tend to get very twitchy if you have a prang with a modified car when they don't know, however well the job was carried out.
And don't forget filling up can be a trial if your nearest Lpg station is 20 miles away.
Opposite my regular service garage on a small trading estate is a unit that specialises in Lpg conversions. Always seems quite busy but, it is noticeable the owner drives a...er! petrol driven Ferrari!!
Experience; is something you gain, just after you needed it most.

When faced with two choices, simply toss a coin. It works not because it settles the question for you. But because in that brief moment while the coin is in the air. You suddenly know what you are hoping for.

Re: Fuel additive Recommend?

Certainly agree about using a fuel addative to clean out the injectors in a diesel car prior to the MOT but in terms of extra mileage I think the AA or some other organisation tested some of these thing out and found they made little or no difference.
Some may even make you car warranty invalid !

Well, I am not a technician, or a member of the AA,. so my "appraisal" is totally independent, and I think it proves that it does give me more MPG....no "test track" can substitute for "actual" mileage on public roads......... so don`t believe all you read in the papers.

Only additive that goes in my tank is the fuel itself!

I've been using Millers diesel additive for over 15 years now...  never any problems, but always better fuel consumption (as measured by brim-to-brim topups at the same pump) and responsiveness. They also do a petrol version if anyone's interested.
